3D Wimpout at Berowra felt bloody hard for 21 the last time I was on it, but I think it's a combo of not having been out in a while and old school thin wall sandstone. Just about anything at the Big K. used to be amusing, but the new guide seems to have added 3-4 grades to everything.

Someone admitted to me that Butter Knives at Berowra might be a touch harder than 26 since it took them 3 months after doing a 29 at Araps in 3 days...

Pitch 2 of Lieben
and pitch 4...
and pitch 5 actually if you go wrong way.
I guess this was the 17 mikl based his grading on?
Resurrection corner at frog is a climb I try to remember when I think something may be 18.

I reckon hangdog has it, now i know climbing isn't all about the grades but when you start out and done a few 17s and get on this beast you don't try it again til you climb twice the grade (22 not 34) and its still bloody hard.

Ballrace (17) at Piddo... I can walk up The Kraken (22) first shot, but fall off Ballrace as my next climb on the same day. Even on subsequent repeats I feel like I'm fighting tooth and nail for the first 8m of that climb.
